17 Claims.

7 The present invention relates to a mechanism for handling material in the form of sheets, that is, forms which have practically onlytwo dimensions, length and width, but no thickness. More {5 particularly our invention is a .mechanism'for tilting material in the form of flat sheets from a horizontal position to a desired angle in order to subject the surfaces to various treatments such as spraying, enameling, sand or shot blasting, 1 and then tilting back to the horizontal.

The general object of our invention is to facilitate the handling of sheet material so as to substantially eliminate any manual operations and to provide a practically continuous, automatic ing a sheet at anangle from the horizontal it is possible to treat one or both surfaces, especially in shot blasting practice.

been made in the construction of the mechanism 2 to incline the sheet at any other desired angle from between the horizontal and vertical positions so as to accommodate any treatment which might be necessary. v

To the accomplishment of, the foregoing and .2 related ends, said invention, then, consistsof the means hereinafter fully described and particularly pointed out in the. claims, the annexed drawings and the following description setting forth in detail certain mechanism embodying the .3 invention, such disclosedsmeansconstituting,

however, but one ofvarious mechanical forms in which the principle of the invention may be used. p

In said annexed drawings:-.-

Fig.1 is a plan view of the general arrangement of the tilting tables, treating mechanism and lateral receiving tables; Fig. 2 is an elevation of one of the tilting tables showing the horizontal and tilting positions; Fig. 3 is an elevation of the tilting table showing its arrangement in position with the lateral receiving. bed; Fig. 4 is a detail of a tilting table showing the means of sheet conveying; Fig. 5 is an elevation of a varied form of construction of the tilting mechanism; Fig. 6 is a plan view of the tilting table showing another form of conveying construction; and Fig. 7 is a plan view of the tilting table arranged in conjunction with the lateral receiving bed. r e For the purpose'of the. present description, th mechanism designed to handle sheet steel for shotblasting treatment will be explained. The sheets from the sheet mill are fed from the live rolls 1, Fig. 1, or other means, onto the face of the tiltable table in horizontal position and are con- It is found that by plac- Provision has also 7 veyed the :le'ngth'thereof by a conveying means which may consist of transverse horizontal shafts 2 with roller elements 3 placed thereon. These shafts may each be power driven by means of bevel gears 26, motivated by shafts 25 which are in turn driven by a mechanism 5, orv they may be vintermittently spaced with idler shafts'2', as

shown in Fig. 4. 'When the moving sheet contacts with the limit switch 6, the longitudinal. conveying means are automatically stopped and a motivating means 15 is set into operation, causing the gears 34 torotate-the gear segment 27, and to arcuately inclinethe table 9 about the stanchion and pivot 8, until the table frame 9 is elevated to the predetermined desired angle. It

may be noted at this point that if it is desirous of tilting these sheets to a complete vertical position, a-structure asshown in Fig. 5.may be'employed which is substantially the same as the structure shown in Fig. 2, except that the arc of gear segment 14' is increased, and retaining idler rolls 12, mounted on the arm 13 are placed in such a position opposite the face of. the conveying rolls 2 that the sheets will be substantially. re- 0 tained on the face of the tilting table. The inclining mechanism, composed of driving means 16- and 16 and gears 29and 30, has been placed in a slightly different position so that it maybe more readily accessible for purposes of service and mr spection. After the table has been raised to the a desired angle, rollers 4 which areflplaced along one side of the table, and whose axes are normal to the plane thereof, are automatically set in motion by a driving means 5 connected to the longi- 0 Y tudinal shafts 36 by meansof bevel-gears 37, Fig.

6, delivering the sheets into the treating mechanism 7. The rolls 4 may also be idler rolls while the conveying motion is supplied by the transverse power driven shafts 2 and rollers 3. After the sheet has entirely entered the treating mecha nism, the table is lowered to receive the next sheet. The sheets after emerging fromthe treating mechanism ininclined position are received by a similar tilting table 10 which is also supplied with conveying means, such as transverse shafts 11, rollers 3 and vertical rollers 17. The-latter rollers may be driven by'means of longitudinal shafts 36 motivated by a prime mover 38, Fig. 7.

- When the entire sheet has passed onto the re-,

ceiving table 10, it is then automatically lowered into a horizontalposition or approximate hori-.-

zontal position as shownby the dotted lines in Fig. 3. On reaching the horizontal position or approximate horizontal position, the sheets may- 1'10 be conveyed forward in a longitudinal direction,

or endless chains 18, traveling around the powerdriven pulleys 33, said chains having dogs mounted thereon at specified intervals, are set in motion with the result that the sheets are moved in a lateral transverse direction onto the bed 19. This lateral receiving bed may be constructed with shafts and rollers, as illustrated in Fig. l, or it may have the construction shown in Fig. 7 where supporting bars 21 and 24 are placed across the face of the table 19 at substantially an acute angle to the direction of motion of the sheets received thereon. The result of the angular position of the supporting bars is that a wiping action is produced on the face of the sheets so that any small foreign particles are removed. These same supporting bars may be incorporated into the construction of the tiltable table 10 as represented plurality of rollers rotatably mounted on one side of such frame with the axes thereof substantially at right angles to the axes of said shafts, means for driving said shafts, and means for effecting arcuate movement of said table.
